Description
Technical field
The invention belongs to composite structure design fields, are related to a kind of manufacturing method of blade tip carbon fiber structural.
Background technology
As national economic strength enhances, make great efforts the development to high-tech areas such as Aeronautics and Astronautics, develop all kinds of boats
My god, aviation aircraft, need to carry out a large amount of wind tunnel test work, meanwhile, the resistance to compression heat resistanceheat resistants of a variety of materials experiment, automobile, height
Fast train, the air drag of ship, heat-resisting and compression test are also required to carry out wind tunnel test.Therefore low speed, transonic speed, ultrasound
Fast, hypersonic all types of wind-tunnel are rapidly developed, up to the present, China possessed low speed, high speed, ultrahigh speed and
The wind-tunnel such as shock wave, electric arc, for the variation to meet the market requirement, the product of my company will also do corresponding adjustment.
Compressor is the core equipment of continous way transonic wind tunnel, and compressor blade therein is crucial in core, is
The overall weight of compressor is reduced, reduces the startup inertia of compressor, composite material relies on its light weight, superior specific strength,
The advantages that specific stiffness, specific modulus and corrosion resistance, gradual substituted metal material became compressor blade first choice.For reduce energy consumption,
Compressor weight and rotary inertia are reduced, using foam sandwich of the carbon fibre composite as the main material of compressor blade
Structure.
Wind-tunnel pipeline is made of metallic conduit, since factors, the blade tip such as deformation need after machining accuracy and assembling
Reconditioning quality, facilitate blade with wheel hub and installation when carry out reconditioning adjustment blade tip and wind-tunnel pipeline gap, reach smooth use
Purpose.Existing structure uses foam sandwich structure because of blade.Blade tip must have filler, and structure is shown in Fig. 1, and reconditioning can make surface layer
Package cloth reconditioning is fallen.Wind tunnel blade has the characteristics that high-revolving operation, and blade tip linear velocity is up to more than 250m/s, operational process
In centrifugal force it is bigger, easily cause filler and blade body separation, cause blade damage.
Invention content
The purpose of the present invention：Present invention aims to overcome that since blade tip package cloth is by after reconditioning, blade tip filler because from
Mental power function and blade body separation, cause blade damage.
Technical scheme of the present invention：A kind of manufacturing method of blade tip carbon fiber structural, which is characterized in that
When blade layer is spread, blade tip carbon fiber package cloth 4 is first spread, outer layer carbon cloth 1 short below foam is spread, by foam 2
It is placed in the laying completed, spreads outer layer carbon cloth 1 short above foam, blade tip carbon fiber package cloth 4, by blade tip carbon fiber
Patch 5 is placed on 2 end face of foam, is wrapped up with blade tip carbon fiber package cloth 4, is docked in upper surface；
Spread the outer layer carbon cloth 1 of middle length above foam, paving blade tip carbon fiber package cloth 4, the foam and carbon fiber completed
Overturning, spreads the outer layer carbon cloth 1 of middle length below foam, and blade tip carbon fiber patch 5 is placed with by paving blade tip carbon fiber package cloth 4
In the leaf apex end surface completed, wrapped up with blade tip carbon fiber package cloth 4, docked in blade lower surface；
The outer layer carbon cloth 1 that paving foam is grown below, blade tip carbon fiber package cloth 4, the foam completed and carbon fiber overturning,
The outer layer carbon cloth 1 that paving foam is grown above, blade tip carbon fiber patch 5 is placed in the leaf apex end surface completed, sharp carbon fiber
Package cloth 4 is wrapped up, and is docked in blade upper surface.
During outer layer 1 blanking of carbon cloth, length etc..
During blade tip carbon fiber 5 blanking of patch, construction profile is paved into stepped consistent with outer layer carbon cloth 1.
During layer paving from inside to outside, foam and carbon fiber are overturn when spreading cloth layer under foam, facilitates and carry out layer paving.
Sharp carbon fiber package cloth 4 is docked in 2 upper surface of placed foam, makes placement surface smooth and layer is facilitated to spread.
Beneficial effects of the present invention：The present invention is the manufacturing method of tip structure, and first then paving is pasted by the layer of cloth of foam
Patch is put, is wrapped up with package cloth, layer is spread successively from inside to outside successively, and package cloth is overlapped on foam upper surface and is docked,
This structure will not be fallen because blade tip wraps up cloth by reconditioning, and reduce blade tip intensity, ensureing blade service requirement simultaneously, reduce with
Blade is used cooperatively the machining accuracy of metallic conduit, and cost greatly reduces.

Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings：
As shown in Figure 2 and Figure 3, a kind of manufacturing method of blade tip carbon fiber structural, outer layer carbon cloth 1 and blade tip carbon fiber
Blanking machine blanking is used during 5 blanking of patch, it is noted that during outer layer 1 blanking of carbon cloth, length etc.；Blade tip carbon fiber patch 5
During blanking, construction profile is paved into stepped consistent with outer layer carbon cloth 1.When blade tip carbon fiber wraps up 4 blanking of cloth, package
Cloth is longer than interfaced package cloth, for docking.
When blade layer is spread, blade tip carbon fiber package cloth 4 is first spread, outer layer carbon cloth 1 short below foam is spread, by foam 2
It is placed in the laying completed, spreads outer layer carbon cloth 1 short above foam, blade tip carbon fiber package cloth 4, by blade tip carbon fiber
